Description

Bei Ventilen normaler Bauart treten infolge pl<itzlicher Änderungen des Strömungsquerschnitts und teilweise scharfer Umlenkungen Wirbelbildungen auf, die zu verhältnismäßig großen Strömungsverhisten führen.With valves of normal design occur as a result of sudden changes the flow cross-section and sometimes sharp deflections on vortex formations, which lead to relatively large flow obscurations.

Gegenstand der Erfindung ist einVentil, welches ini ganz geöffneten Zustand auf dem ganzen Strömungsweg einen Durchgangsquerschnitt von gleichbleibender Größe aufweist und in welchem (las strömende Mittel möglichst geringe und dabei stetig verlaufende Umlenkungen erfährt, so daß die @\'irbelbildung weitgehend vermieden und damit ein niedriger Strömungsverlust erreicht wird.The invention relates to a valve which, when fully open Condition a passage cross-section of constant over the entire flow path Size and in which (read flowing means as small as possible and at the same time undergoes constant deflections, so that the formation of vortices is largely avoided and thus a lower flow loss is achieved.

Während bei Ventilen normaler Bauart das Mittel durch die Ebene des Ventilsitzes gegen die Unterseite des Ventiltellers strömt, trägt das Verschlusstück des erfindungsgemäßen Ventils einen in (!en Durchflußquerschnitt am Ventilsitz hineinragenden Ansatz, der zusammen mit der Gehäusewand unterhalb des Ventilsitzes einen S-förmigen 1)urchflußkanal ergibt.While with valves of normal design the means through the plane of the Valve seat flows against the underside of the valve disk, carries the closure piece of the valve according to the invention has a protruding flow cross section on the valve seat Approach which, together with the housing wall below the valve seat, has an S-shaped 1) flow channel results.

Dadurch erfährt das Mittel bei seinem Fluß durch die Ventilsitzebene eine verhältnismäßig sanfte und stetige Umlenkung. Der Querschnitt des Durchflußkanals weist bei geöffnetem Ventil auf (lern ganzen Strömungsweg von einem Anschlußflansch zum anderen gleichbleibende Größe auf. Zweckmäßig wird der Durchflußkanal am \'ctttilsitz rechteckig ausgebildet. Das Verschlusstück 3 kann dazu, wie die Abbildungen zeigen, \\-ie ein Kolben in einem zylindrischen Gehäusemittelstück i gleiten und gabelförmig ausgebildet sein und mit seinen beiden Wangen über ein Einsatzstück 2 greifen, so das die Innenflächen der beiden Wangen die Seitenwände des rechteckigen Durchflußkanals bilden. Die Anschlußkanäle im Gehäuse, die am Flanschaustritt runden Querschnitt haben, gehen dann zum Verschlusstück 2 hin in einen rechteckigen Querschnitt über. Die Abdichtung des Ventils in der Schließlage erfolgt durch das Aufeinanderpressen der beiden Ringe 5, die aus einem dem Verwendungszweck des Ventils angepaßten Werkstoff gewählt werden. Der untere Ring, der den Ventilsitz bildet, sitzt fest im Gehäuse, der obere auf dem Verschlußstück. Das Einschleifen des Ventilsitzes kann mach Herausnahme des Einsatzstücks 2 in bekannter Weise erfolgen. Das Verschlußstück wird mittels Spindel betätigt, die durch den Deckelflansch 4 geführt wird, welcher Stopfbüchee und Spindeldrücke trägt.As a result, the agent experiences its flow through the valve seat plane a relatively gentle and steady diversion. The cross section of the flow channel shows when the valve is open (learn the entire flow path from a connecting flange on the other hand, constant size. The flow channel at the \ 'ctttilsitz is useful rectangular shape. The locking piece 3 can, as the figures show, \\ - ie a piston in a cylindrical housing center piece i slide and fork-shaped be designed and grip with his two cheeks over an insert 2, so that the inner surfaces of the two cheeks the side walls of the rectangular flow channel form. The connection channels in the housing, the round cross-section at the flange outlet have, then go to the locking piece 2 towards a rectangular cross-section. The valve is sealed in the closed position by being pressed against one another of the two rings 5, which are made of a material adapted to the intended use of the valve to get voted. The lower ring, which forms the valve seat, sits firmly in the housing, the upper one on the breech block. The grinding in of the valve seat can make removal of the insert 2 take place in a known manner. The closure piece is by means of Actuated spindle, which is passed through the cover flange 4, which stuffing box and spindle pressures.
